目前我国海带养殖面积约15万hm2,年产干品27万t,占世界海藻总产量的50%。三十烷醇(TA)乳粉可显著提高海带的产量和品质,海带苗经2mg/LTA浸泡2h后放养,能促进假根生长,提高保苗率,增加叶绿素、岩藻黄素含量,促进碳、氮代谢,增加干物质积累。处理比对照平均增收干品657t/hm2,增产率为35%。同时,海带可比对照增收碘2424kg/hm2、褐藻胶1665t/hm2、甘露醇1278t/hm2。TA乳粉属国内外首创,具有无毒、高效、成本低、不变质及贮运方便等优点,已在全国海带上推广16万hm2,创经济效益3亿多元。
At present, China’s kelp aquaculture area of about 150,000 hm2, with an annual output of 270,000 t dry goods, accounting for 50% of the world’s total seaweed production. Triacontanol (TA) milk powder could significantly improve the yield and quality of kelp, kelp seedlings by 2mg / LTA soak 2h after stocking, can promote the growth of the pseudo-root, increase the seedling protection rate, increase the content of chlorophyll, fucoxanthin and promote carbon , Nitrogen metabolism, increased dry matter accumulation. The average increase of dry matter processing than the control 657t / hm2, the yield was 35%. At the same time, kelp than the control to add iodine 2424kg / hm2, alginate 1665t / hm2, mannitol 1278t / hm2. TA milk powder is the first domestic and foreign, with non-toxic, efficient, low cost, non-deterioration and storage and transportation advantages, has been in the country to promote 160,000 hm2 kelp, creating economic benefits 300 million yuan.
